In 1720, Bach returned home after a long road trip to find that his wife had died and had already been committed to the cold ground. Shortly after, he began composing the six suites and partitas for unaccompanied violin. The completed final manuscript in his handwriting is titled, “Sei Solo. Violino senza Basso accompagnato.” Most of us take that to mean in Germanish Italian, “Six solo pieces for violin, without accompaniment.” But in Italian, “Sei solo” means, “You’re alone.”
